It likes to fall asleep when left idle for long enough. Sometimes it wakes moderately promptly, sometimes you could be waiting for well over 30 seconds for it to wake up. It seems to have two powerdown modes. I've stood there and waited, well beyond my patience, for the drive to wake up while I was trying to reboot or shut down the laptop connected to it. The drive had fallen asleep, and Fedora wasn't going to shut down until it synced the drive. That could be similarly problematic if you're trying to use the drive, while it's away with the pixies. So far as I could tell, there was some Windows software to change the timeout/sleep options, but it didn't set something in the drive enclosure that would change how it behaved forever more. It was something that needed to be set each time the drive was powered up. They all presume you're using Windows, and that if you're not happy with the defaults, you'll run some Windows app every time you start your computer, to twiddle things. The transfer rate was far from best speed that USB2 can manage, though I haven't tested whether that was down to Nautilus (being used to copy files over), or the interface (I haven't used anything else to copy files, to compare). The only redeeming feature was that it didn't use one of those crappy power bricks - the rectangular box in the middle of a cord, with a really fragile 4-pin connector to connect to the drive. Every one of those, that I've used, got stinking hot, and produced so much electrical hash it would cause my ADSL modem to disconnect (two different modems, one brand new). The Seagate used one of those wall wart power plugs (which annoy other people, because they don't fit next to other things in a four-way power board). My advice: Find some generic interface without timeouts built into it. Look for an enclosure with good heatsinking and airflow that doesn't rely on a tiny crappy fan. And, especially for permanent external devices, ones where a main cable plugs straight into the drive box, seem more practical. And, if it really is a *permanent* addition, can you not put a normal drive into the computer, instead? -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored.
